Thank you for the link. I have purchased Issue 19 and now have the drawings. There does not seem to be a dimension for the overall length of the body. What overall length did you make yours? I’m looking forward to possibly redesigning it for ease of manufacture and making it.
Sorry, just noticed this. Mine is 3.5".
Thank you I have purchased issue 19 and have produced a 3D model and a set of detail drawings. Instead of having to produce a square hole I am going to machine a slot and fit a retaining plate to secure the adjusting bar in place. All my designs are in metric.
Finally completed my version of the spring winder. i have replaced the square hole in the body with two guide pins.

Looks really good. When I wind springs, If I need 4 springs, I wind them all at one time. That way there all the same and you just cut them apart.

I saw that video some time ago.
However is the hand cranked item easier to use?

Having seen Andrew Whales video I made one of these and found it difficlt to use because you are trying to locate the round part of the tool onto a round mandrel. I managed to overcome this by replacing the round wedge item with a flat plate with a bee machined into it. The problem with this arrangement is you require different thicknesses of plate for different spring pitches. However I also found difficulty in holding the tool with one hand and using the other to control the lathe.
What I like about Jerry’s version is that you have complete control when making a spring and it provides a clamping facility for the spring and the spring pitch is infinitely variable. The one that I made removes the requirement for a square hole, but if you have a broaching capabi it would be less of a problem. I am developing a second version which removes the requirement to drill the deep hole through the body.
hope this helps
